AI coding makes CI a bottleneck, reworked
The gist
Linear reworked its CI pipeline after AI agents outran it.
The fix matters to any team whose AI-generated code now outpaces its tests.
How it unfolded
- Sep 18, 2026An article on top AI tools for CI/CD pipeline automation is published, advising teams to start with the bottleneck rather than the tool.
- Sep 21, 2026Linear publishes "AI coding has made CI a bottleneck, so we reworked ours to keep up," authored by engineering's Mufeez Amjad, saying agents were shipping code faster than its CI pipeline could keep up.
- Sep 21, 2026Linear reports a roughly 15% faster test suite and a 50% reduction in runner time per test while the test suite grew 4x in size; PR wait time fell from more than six minutes to just over five.
